Specification of Letters Patent. 1'

Application led January 4, 1918. iierial` No. 210,324.

To all whom t may concern.'

Be it known that I, HARRY A. Bownisii, a citizen of the United States residing at Eagle Pass, in the county of Maverick and State of "Texas, have invented certain new and useful Improvements in SpeedRecord ers, ofwhich the following is 'a specification.

This invention has relation to recording instruments, and has for an object to provide an instrument for use in connection with motor vehicles, orl other self-propelled.

conveyances whereby to permanently record upon a strip of moving paper the `speed of the conveyance at any instant during the period of travel thereof.

Another object of the invention is to provide a recording instrument for the purpose above described adapted for association with a standard time piece, and a speed registerling instrument and embodying means operable by these two devices for permanently recordin the speed of the conveyance at any instant uring travel thereof in the manner above set forth.

Another object of the invention is to provide a recording instrumentv having the above named characteristics embodying a casing, and a frame movably mounted therein for positioning p from a position within the casing to a position without, said frame supporting the rolls of papers and actuating mechanism therefor, with means operable by thetime piece and speed registerin mounted for movement across the surface of the paper.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of the correlative parts, to be hereinafter more fully scribed and particularly set forth in the appended claims.

In the accompanyin drawings in which similar and correspon ing parts are designated by the same characters of reference throughout the several views in which they appear;

Figure 1, is a view in front elevation of a recording instrument constructed in accordance with my invention illustrating they cover removed.

Witli reference to the drawings, 10 indicates a casing having right and left hand side walls lland 12 respectively, the casing being divided by a vertical partition 13 delining a paper winding mechanism containing compartment 14, andan instrument compartment 15.

Mounted within the paper winding mecha- Patented July 27, 1920.

nisni compartment 14 is a frame comprising side plates ltidwhich support therebetween ata point intermediate the ends of the plates a shaft 17 which is fixedly held in the plates and which support loosel a drum 18 having a flange 19 at one end ormed with a serrated periphery for engagement by means of a pawl 20 pivotally mounted upon the inner face of one of the side plates.u A coil spring 2l is inclosed within the drum with the inner end of the spring connected to the shaft 17 and the outer end connectedto the interior surface ofthe drum as clearly Shown in Fig. 3. The surface of the drum is grooved longitudinally as at 22 to receive a wire 23 whereby one end of a strip of paper ma be clamped beneath the wire.

he plates 16 also suppport a` roller 24 designed to support a roll of paper 25, one end of which paper, indicated at 26, maybe passed around a roller 27 positioned between the 4lower ends of the plates and loosely mounted upon a shaft 28, the paper being then extended upwardly and partly around a roller 29 fxedly mounted upon a shaft 30' journaled in the side plate. Said sha-ft 30 carries upon its end projecting beyond the outer face of one plate 16 a gear wheel 31 which is designed for meshing engagement with a gear wheel 32 mounted upon a shaft 33 which is journaled in the partition 13 mentioned above. The side plates 16 forming the frame are mounted upon a rod 33 extended across the front of the casing whereby the frame may be pivotally mounted on said rod for movement from a osition within the casing as indicated in Fig. 3, to

a position without the casing as indicated in Fig. 4. The upper end of each plate is formed with outwardly extending lugs 34 which are engageable by springs 35 secured to the inner face of a cover plate 36 hingedly connected as at 37 to the lower edge of the compartment 14. The springs,` when the cover plate is in la closed position, by ressing against the lugs 34 retain the .rame within the casing andalso act to retain the gear wheels 31 and 32 in engagement.

A groove is formed in the inside surface of the front wall of the casing below the door 36, and a block 38 having a dovetailed portion is seated in the groove.' rThe lower end oi a vertical stylus arm 41 is connected to the block and a stylus or pen 42 is provided at the upper end of the arm for engaging the stretch of paper between the rollers 27 and 29. 0 paper after passing around the roller 29 1s engaged by a roller 43 mounted upon the shaft 33, the pressure of the spring 35 or the cover acting to retain said rollers in engagement with the paper, the end `of the paper being then trained around the drum 18 and engaged beneath the wlre 23 in the manner described above.

A roller 44 is mounted on the iront edge of the wall 11, a pair'of rollers 45 and 46 being mounted at a point opposite the'roller 44 and upon a wall 47 provided within the instrument containing compartment 15. A grooved drum 48 is also mounted onsaid wall 47 and a pair of rollers 49 and 50 are vmounted above and below said drum,

the drum being loosely mounted upon a.

shaft 51 secured to said wall 47. An endless element, such as a wire or the' like indicated at 52 is provided, being passed once around the drum 48, and one stretch passed around the roller 49, thence around the roller 46 to the roller 44, around the 'same returning along its other stretch around the rollers V45 and 50 and back to the drum 48. A pinion 53 is mounted for rotation withl the drum 48 and for meshing engagement with a pinion 54 loosely mounted-upon a stud 55 pro'ecting from the wall 47, said pinion 54 eing in meshing engagement with a pinion 56 which is movable coincidently with the movement of the pointer of a conventional automobile speed indicating instrumentor speedometer shown at 57.

The shaft 83 mentioned above which is j ournaled in the partition 13 extends into the compartment 15 and is provided with a bevel gear 58 in meshing engagement with a bevel gear 59 mounted upon a vertical shaft 60 which is journaled in bearingsv 61 mounted upon a wall 62, the lower end of said shaft carrying a bevel gear 63 which meshes with a similar gear 64 mounted upon a short horizontal shaft 65 also journaled in bearings 66a which are mounted upon the wall 62. A pinion 67 is mountedon said shaft 65 for engagement with a pinion 66 which is operable by the mechanism of a vtime piece indicated at 68.

lt will be noted that the.

In operation, the speedometer 57 is connected as usual to the front wheels of a vehicle in which the speed recording mecha- 'thereof actingthrough the flexible element 52 oscillates the pointer arm 41 and aline is inscribed upon the strip ot moving paper 26. rllhe motion of the time piece actuating mechanism is uniform andcontinuous, motion of the pinion 67 being transmitted to the pinion 66, and 'thence 'through the pinions 64, 63, 59 and 58 to the'roller 43. rThe paper, being held between said roller 43 and the roller 29 is uniformly withdrawn from the roller 25, and the slaclr in the paper after passing between said rollers 43 and 29 is taken up by the drum 18 8.' owing to the provision of the spring 21 therein. The paper is thus moved continu ously and uniformly, and during travel oi1 the machine the speed thereof at any in- -stant is permanently recorded. 94

l/Vhile l have illustrated and described my invention with some degree of particularity, l-realize that in practice various alterations thereover may be made, and l therefore desire to reserve the right and 9 vprivilege of changing the or'mV of the details of construction, or otherwise altering lthe arrangement of the correlativo parts without departing from the spirit of the invention or the scope of the appended 1 claims.

Having thus described my invention what l claim as new and desire to secure by Letters Patent is 1. A recording instrument comprising a 1 casing divided into two compartments, a'

hinged door ffor closing one of the compartments, a spring secured to the inner face of the door, a frame pivotally mounted within the compartment having the. door 1 and adapted to be engaged by the spring on the door, means mounted in said frame for actuating a'strip vof paper and including a roller, a pressure roller mounted in said casing, and with which said frame car- 1 ried roller contacts, being held engaged by said spring, a pointer mounted in said frame for movement across the paper, said pointer actuated by a standard speedometer, gearing in the other compartment actuated by a standard time piece, and means asso-v ciated with said gearing for operating the paper actuating mechanism.

2. An instrument of the class described comprising a casing divided into compartl ments, one of which is equi'ped withV an outwardly opening door, a rame pivoted in said door-equipped compartment to swing outwardly on the opening of the door, a spring controlled drum mounted in l said drum in said said frame, e pair of contacting rollers positioned above said drum, one being carried by the frame and the other by the casing, a paper cerryin roll mounted below rame, a paper guide mounted in said frame, the paper fed from said roller being secured to said drum and passed around said guide and between the first-mentioned rollers, and means carried by said door for holding said frame in op- 10 erative position, and the first-mentioned rollers contacting.

In testimony whereof I `*affix my signature in presence of two witnesses. l HARRY A. BOWDISH. ``\7Vitnesses:
